Just a thought here. Lets take that statement and add a twist to it and see how/if it stands on it's own merits.
What if the owner of a business was to post a "No Blacks allowed, Whites only" sign. Isn't he guilty of discrimination, isn't he ethically and morally wrong. The word discrimination can be associated and applied to a host of situations many of which are the same if taken at face value, but inherently different upon closer inspection.
The "NO WEAPONS" signage itself is a form of discrimination against the law abiding citizens that lawfully carry concealed weapons.
